One of the things I've really enjoyed on several AVS Forum boards is when a discussion thread revolves around a particular manufacturer. For example there are terrific Audyssey and D2 threads that have that character, and there was a nice Q&A over several days with the guy that leads Krell. The Moderators keep the anti mfg flames out of those threads. For example, not once have I seen an Audyssey poster flame a D2 room correction poster, or vice versa.
It's a nice way of having an intelligent ongoing dialogue with an intelligent manufacturer, while keeping the manufacturer vs. manufacturer diatribes down.
